To all whom t may concern.-

Be it known that we, FREDERICK G. SAR- GENT and ALLAN C. SARGENT, ofGraniteville, in the county of Middlesex and State of Massachusetts,have invented a new and useful Improvement in Wire-Cloth Aprons, ofwhich the following is a specification.

Our improvement relates to aprons made in the form of screens of wirefor the purpose of drying articles on them, and other similar purposes,and it Consists in certain new and useful constructions and combinationsof the several parts thereof, substantially as hereinafter described andclaimed.

In the drawings:-Figure l showsa wire screen apron passing aroundrollers, in the position in which it would be used in driers and othermachines. Fig. 2 shows a section of this apron in face view with ourconstrucf tion illustrated, and also a modification thereof in the formof an apron with diamondshaped meshes in face view. Fig. 3 shows theapparatus and illustrates the method of making the apron according toour invention.

A is a wire screen apron having square meshes, which is made endless andpasses over the rollers, l, 2, which are mounted on the axes, 3, 3, inthe ordinary manner. These rollers are such as are used in driers andwool washing machines, and others of like character. Heretofore whensuch aprons were woven out of ordinary wire, or wire which had beenpreviously tinned or galvanized, it has been found that owing to theunequal strain and play of the wires upon each other these aprons areliable to get out of shape, one side becoming longer or shorter than theother, and the wires getting outofl place which run crosswise of theapron, so that they would tend to run oft' ofthe rollers at one end andbind and Wear upon the ends and casing of the machine, and rapidly Wear0E. the tinning or galvanizing in places and wear them out and speedilybecome either entirely useless' or of comparatively little value. On theother hand, when such aprons have been made of Wires woven togetherasillustrated and dipped in the tinning or galvanizing metal afterward thescores where the Wires cross become all filled with the metal andcemented or soldered together, and this renders them too stift to passaround the rollers of moderate size, which require, on account of theirsmall diameter, that there shall be some play between the wires at thescores in order to allow the apron to pass freely around them.

Our improvement consists in Weaving the wire apron up rst of Wires inthe form'shown and then in tinning or galvanizingthe scores of the aprontransversely at considerable intervals, of some of the wires, leavingthe intermediate scores without being galvanized after the weaving isdone, so that While the apron is held together by this process atintervals sufficiently near to prevent the undue straining of one sidemore than the other, or the displacement of the wires, it shall yetpossess the requisite flexibility and yielding properties in passingaround the rollers. In an apron similar to the one lettered A thisgalvanizing or tinning after the weaving is done leaves the wiresslightly larger, and in Fig. 2 this slight enlargement has beenexaggerated in the transverse wires in order to better illustrate ourinvention. The scores in the enlarged wires, 5, 5, are the ones whichhave been tinned or galvanized after the apron was woven, and it will beseen that at intervals they tie the apron together from side to side onthree of the adjacent transverse wires. This holds the two sides of theapron at intervals and all the intermediate sides transversely on threewires so that they cannot get misplaced, and an interval of six wires islet't between every three that are galvanized or tinned after theweaving, which six wires have the intermediate scores between the edgesloose so that they can have some play or movement. Ve do not intend tolimit our invention to exactly this number of tinned or galvanizedscores, separated by exactly this number of loose scores, because aconsiderable variation may be made in these particu lars withoutdeparting from our invention.

In Fig. 3 is shown the apparatus for performing the process of tinningor galvanizing the apron at intervals. We describe the apparatus we useat some length, because ordinary tinning or galvanizing apparatus willnot serve to tin or galvanize the precise scores desired at intervals,without liability of getting the tin or zinc on the wires or scores be-IOO tween, which would impair the utility of the invention with thegiven size of roller with which it is to be used. The apparatus shown isone which can be readily modified so as to tin or galvanize a greater orless number of adjacent scoresin the wire apron at pleasure. 10 is atrough, having the melted metal lling it to the height of the dottedline. A beam, 11, is provided with handles, 12, 12, at each end on itsupper edge and is of su tticient depth to reach to the bottom ot thetrough when dipped downward therein. On this beam are attached two crossbars, 13, 13, which hold the rods, 14, projecting downward, and twobars, 15, 15, are attached to the rods parallel to beam, 11, at a littledistance below the top of the same. The wire screen apron, A, is passedover bar 15 on one side under the rounded lower edge of beam, 11, and upover bar 15 on the other side, presenting two or three lines of scorestransversely of the apron on the lower edge of the beam l1. The beam,11, is then dipped into the galvanizing metal, effectively tinning orgalvanizing these scores according to the metal used, when the apron isdriven along over bars, 15, and under the beam the proper distance andthe beam is again dipped into the metal, and so on until the entireapron is subjected to the process. B (Fig. 2) is a wire screen apronwoven with its scores in diamond shape. The scores marked 5 will besoldered or cemented together by the dipping at intervals in the sameway as with the apron, A, when subjected to the processin a similarmanner. The result in either case is that the apron will not yield apronwith the apparatus shown in Fig. 3, will melt the tin or galvanizingmetal on the wires and scores which are dipped into the molten metal inthe trough and eectively solder or cement them together in a superiormanner.

What we claim as new and of our invention 1. A flexible woven wire apronhaving its scores in alternate transverse portions secured bygalvanizingor tinning, and in intermediate portions free to move or iiex,substantially as described.

2. A iiexible woven wire apron having its wires protected by galvanizingor tinning throughout its length, and having its scores in alternatetransverse portions secured by galvanizing or tinning, and inintermediate portions free to move and dex, substantially as described.
